什么决定了 Tkinter Text 小部件的大小? [英] What determines the size of a Tkinter Text widget?

问题描述

我正在尝试缩小文本小部件的宽度以适应内容.

如果我使用，

<预><代码>>>>tktext.config(宽度=250)>>>tktext.winfo_width()650

为什么会这样?决定小部件宽度的所有因素是什么?

解决方案

您看到差异的原因是:

1. width 选项以字符单位*为单位设置文本框的宽度.
2. .winfo_width方法返回以像素为单位的宽度.

这两个不一定必须相同(很少是相同的).

*注意:我找不到 Tkinter.Text width 选项的好链接，所以我添加了一个对于 Tkinter.Entry width 选项，原理相同.

I\m trying to shrink the width of my Text widget to fit the contents.

if I use,

>>> tktext.config(width=250)
>>> tktext.winfo_width()
650

Why does this happen? What are all the factors that determine a widget's width?

解决方案

The reason that you are seeing the discrepancy is thus:

1. The width option sets the width of the textbox in character units*.
2. The .winfo_width method returns the width in pixels.

These two do not necessarily have to be the same (and rarely are).

*Note: I couldn't find a good link for the Tkinter.Text width option, so I added one for the Tkinter.Entry width option, which has the same principle.
